64 Notes to the consolidated statement of cash flows. Deutsche Telekom paid EUR 1.4 billion to Elektrim and Vivendi in the first quarter of 2011. This gave Deutsche Telekom full, undisputed ownership of PTC (PTC transaction). In accordance with the standards governing statements of cash flows, this total consisted of the following: EUR 0.4 billion net cash from operating activities, EUR 0.8 billion net cash used in investing activities and EUR 0.2 billion net cash used in financing activities. Net cash from operating activities. Net cash from operating activities in the first quarter of 2011 decreased by EUR 0.6 billion compared with the prior-year period to EUR 2.7 billion. In ad- dition to a decline from operations, this was attributable to the following cash flows: payments for the PTC transaction of EUR 0.4 billion, for which there was no corresponding item in the prior-year quarter, and a reduction in the level of receivables sold (factoring) of EUR 0.2 billion compared with the first quarter of 2010, and EUR 0.2 billion higher interest payments. These effects were partially offset by dividends received from the Everything Everywhere joint venture in the first quarter of 2011 amounting to EUR 0.3 billion. The remaining changes in net cash from operating activities consisted of various partially offsetting effects. Net cash used in investing activities. Net cash used in investing activities totaled EUR 2.8 billion as compared with EUR 1.8 billion in first quarter of 2010. This increase was mainly attributable to an increase of EUR 0.5 billion in payments for the acquisition of companies. While cash outflows for the acquisition of STRATO in the first quarter of 2010 totaled EUR 0.3 billion, the cash outflows relating to the PTC transaction in the first quarter of 2011 amounted to EUR 0.8 billion.
